I bought the below, Model: GABA Product Name: Gamma-Aminobutyric Acid Type: Natural Size: 450g Unit Price: AUD $33.10 Quantity: 1 Delivered after 3 days (Melbourne to Sydney transit). Not sure if the product is working for sleep at the moment, first time I took it i felt a little drowsy but effects wore off abit, might need to up the dosage. They had a security alert saying credit card scammmers may be playing up on their site, it was good/honest of them to warn their customers, however it may put people off buying from their website abit.
